Abstract

The utility model relates to a bowling-bowl automatic returning-back accelerator which belongs to the field of culture and sporting goods. A transmission system is driven by a driving motor (1), and a front roll (13) is driven by a back roll (11) through an accelerating belt (12). The front roll is assembled on a floating head (14) in a pressure adjustable type through a front roll frame (6), and the bowling-bowl (38) is rolled forwards when pressed and accelarated by the accelerating belt (12). When the peak is away from the right lower part of the front roll (13), the roll automatically floats downwards, when the upper edge of the back side is punched, the bowling-bowl accelerates again. The utility model has the advantages that the bowling-bowl (38) can be accelerated as soon as possible without enhancing the potential energy of the bowling-bowl, and the ball-return time is shortened. The bowling-bowl automatic returning-back accelerator also has the advantages of stable running, easy adjustment, good maintenance, long service life, simple structure, easy manufacture and low cost.

Description

A kind of bowling automatic return accelerator

The utility model belongs to the cultural and sports facility field, relates to a kind of bowling automatic return accelerator.

In the prior art, the bowl returning accelerator is by transmission mechanism bowling (hereinafter to be referred as ball) extruding to be quickened, put in place along S type guide rail and guide wheel lifting again, relying on kinetic energy and potential energy to rush at return along the transition slideway automatically then returns, its weak point is that noise is big, mechanism's complexity, the cost height, and return of serve speed is slower; Other has Chinese patent 972313478 disclosed schemes, utilize working cylinder to drive connecting lever and corresponding mechanism, extruding, acceleration, lifting, also be to rely on the kinetic energy and the principle of potential energy, its weak point is: return of serve speed is slow, especially adjacent twice pitching utmost point blanking time in short-term, the two is " collisions " easily, leans on the return of serve time of latter's pitching to be greatly affected.

The purpose of this utility model is, a kind of bowling automatic return accelerator is provided, and need not to improve the potential energy of ball, just can smoothly ball be quickened as early as possible, have adjustable unsteady hair style and quicken roller, the moment that makes ball leave accelerator can also be subjected to by the power of " playing " forward, quicken again, thereby shorten the return of serve time greatly, reliable steady, easily adjust maintenance, long service life, simple in structure, easily to make, cost is low.

Concrete scheme of the present utility model is as follows:
